The OPB733TR device uses a lensed infrared LED and phototransistor elements to collimate the light beam to give it an optimizing detection range from 10 to 25.4 mm and a minimum output current of 100 mA that eliminates the need for external amplification of the output signal. It also delivers a peak emission wavelength of 890 nm, a output on-state collector current of 0.1 mA at 12.7 mm from the target and a 20 mA forward current and VCE of 5 V. Its rise and fall time is 15 mS.

The sensor features a molded dark epoxy package to minimize ambient visible light interferences. Its surface mount package is reflow solder compatible to 260 °C. It is available in 16 mm tape on 7-in. diameter reels with 500 pieces per reel.
